It's going down tonight on Little Women: Dallas! In an exclusive clip obtained by In Touch, Tiffani Chance and a pregnant Emily Fernandez get into a heated discussion about Emily's boyfriend and baby daddy, Lontel Johnson, and his alleged arrest.

"I'm not talking s--t!" Tiffani said. "All I f--king said was that I'm concerned. You're about to have another baby." Watch the clip below to see Emily hit Tiffani in the mouth!

Emily's son JJ died at three months old in August 2016 due to the health complications he experienced before and after he was born, including seizures, blood around his brain and loss of vision and hearing. Now, she's expecting her second child with Lontel.

In September, Emily opened up to In Touch about mourning the loss of her son in the public eye. "It was extremely difficult because when he passed away, it had not played out yet on the show. People were still coming up to me asking how he was doing and what was going on — because on TV he was still in the hospital recovering and there was definitely a time we never expected anything like that to happen. It was hard, [with] people talking to [me] — and I didn't want to be rude, but at the same time, I would break down," she explained.

Emily — who originally stems from the Little Women: Atlanta franchise — did offer some wise words to parents who may experience the same heartbreaking situation. "At the end of the day, no matter what the doctor says, go with what your heart says and don't give up. Basically, he lived for three months, they told me the first month that it was pointless and he's never gonna get anywhere — and to me, I didn't care what they said," she recalled.
